Positive Integers Represented by Regular Primitive Positive-Definite Integral Ternary Quadratic Forms

Abstract

In 1997 Jagy, Kaplansky and Schiemann determined that there are at most 913 (classes of) primitive, positive-definite, integral ternary quadratic forms $ax^2 + by^2 + cz^2 + dyz + ezx + fxy$ which are regular. In this paper the positive integers represented by these 913 ternary forms are given.
